Think-aloud protocols are a dominant method in usability testing. There is, however, only little empirical evidence on the actual validity of the method. This paper describes an experiment that compares concurrent and retrospective think-aloud protocols for a usability test of an online library catalogue. There were three points of comparison: usability problems detected, overall task performance, and participant experiences. Results show that concurrent and retrospective think-aloud protocols reveal comparable sets of usability problems, but that these problems come to light in different ways. In retrospective think-aloud protocols, more problems were detected by means of verbalisation, while in concurrent think-aloud protocols, more problems were detected by means of observation. Moreover, in the concurrent think-aloud protocols, the requirement to think aloud while working had a negative effect on the task performance. This raises questions about the reactivity of concurrent think-aloud protocols, especially in the case of high task complexity.

The marketing success of green products has spawned the phenomenon of greenwashing, but studies on the effects of greenwashing on consumers are still limited. Using a 4 × 2 randomized experimental design, this study examines such effects by determining whether consumers respond differently to greenwashing, silent brown, vocal green, and silent green organizations selling hedonic products (perfume) or utilitarian products (detergent). The results show that consumers recognized the green claims in the greenwashing condition, which led to an environmental performance impression in between green and brown organizations but also to more negative judgments about the integrity of communication. Regarding purchase interest, greenwashing organizations performed similarly as silent brown organizations, with significantly lower scores than those of vocal green and silent green organizations. No significant effects of product type and no interaction effects were found. Overall, greenwashing has only limited benefits (perceived environmental performance), poses a major threat (perceived integrity), and has no true competitive advantage (purchase interest).

Although corporate greenwashing is a widespread phenomenon, few studies have investigated its effects on consumers. In these studies, consumers were exposed to organizations that boldly lied about their green behaviors. Most greenwashing practices in real life, however, do not involve complete lies. This article describes a randomized 3 × 2 experimental study in the cruise industry investigating the effects of various degrees of greenwashing. Six experimental conditions were created based on behavioral-claim greenwashing (an organization telling the truth vs. its telling lies or half-lies) and motive greenwashing (an organization acting on its own initiative vs. its taking credit for following legal obligations). Dependent variables were three corporate reputation constructs: environmental performance, product and service quality, and financial performance. Compared to true green behavior, lies and half-lies had similar negative effects on reputation. Taking credit for following legal obligations had no main effect. Only in the case of true green behavior did undeservedly taking credit affect reputation negatively. Overall, the findings suggest that only true green behavior will have the desired positive effects on reputation.

Several studies have focused on the effects of corporate social responsibility (CSR) fit on external stakeholders’ evaluations of CSR activities, attitudes towards companies or brands, and behaviors. The results so far have been contradictory. A possible reason may be that the concept of CSR fit is more complicated than previously assumed. Researchers suggest that there may be different types of CSR fit, but so far no empirical research has focused on a typology of CSR fit. This study fills this gap, describing a qualitative content analysis of the congruence between six organizations and their various CSR activities. Ten annual reports and CSR reports were analyzed, and 102 specific CSR activities were identified. The results show that two levels of fit must be distinguished: based on the means for and the intended ends of the CSR activity. Furthermore, six different types of fit were found, focusing on (1) products and services, (2) production processes, (3) environmental impact, (4) employees, (5) suppliers, and (6) geographical location. Considering the above variety of fit possibilities, the findings emphasize the role of CSR communication as a means of creating fit perceptions.
